The full story

The author can't play piano but has always wanted good-sounding MIDI files made from sheet music, and existing software rarely sounded expressive. This experiment has an LLM read a score written in BANA Music Braille Code. Braille music spells out every note precisely, which makes it easier for a model to read accurately than printed notation. The model then produces an expressive MIDI performance. The demo is Gottschalk's Grande Tarantelle, Op. 67, in Espadero's solo-piano arrangement.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
